e4od slipping

[slowcatdriver]

For about the last year my 97 F350 E4OD will occasionally not engage when I put it in D. If I rev it it will slowly engage and then works fine. When it it doesn't engage I can shift to 1 and it hooks right up. Reverse works fine. It's very intermittant but seems worse after I've been towing or when I'm shifting back and forth between D and R backing a trailer. Last time I changed the filter it seemed like the filter pickup tube didn't fit snugly. Any ideas?

Sounds like your drive band is on it's way out or the front pump is weak. It works in direct 1 because the PCM sends full hydro power in the direct settings and not the metered hydro power. Start saving money for a rebuild...

Whe your transmission is slipping, time to get building.
